Introduction

This tip is example to test android form controls. One test case for test default values, the orther for changed values.

Environment

OS: linux
java: 1.7
IDE: eclipse
robolectric 2.0 alpha 2

Step 1. Create android application by eclipse 

    Application Name: a3
    Project name: a3
    Package: com.example.a3

Step 2. Create form controls

Edit layout activity_main.xml as following: 
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ScrollView01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:scrollbars="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        

        <TextView
            android:id="@+id/TextViewTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/feedbacktitle"
            android:textSize="10pt" >
        </textview>

        <EditText
            android:id="@+id/EditTextName"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:hint="@string/feedbackname"
            android:inputType="textPersonName" >
        </edittext>

        <EditText
            android:id="@+id/EditTextEmail"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:hint="@string/feedbackemail"
            android:inputType="textEmailAddress" >
        </edittext>

        <CheckBox
            android:id="@+id/checkBox1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="CheckBox" />

        <RadioButton
            android:id="@+id/radioButton1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="RadioButton" />

        <ToggleButton
            android:id="@+id/toggleButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textOn="Vibrate on"
            android:textOff="Vibrate off"/>

        <Spinner
            android:id="@+id/planetsSpinner"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />

        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:hint="Touch for submit"
            android:text="Submit" />

    </linearlayout>

</scrollview>

The layout also includes TextView, EditText, Checkbox, Button, RadioButton, ToggleButton, Spinner. These controls are used to demo some simple ideals to test. The button1 is used to perform a changed action by a trigger from user.

Step 3. Set some values for test.

Edit MainActivity.java 
package com.example.a3;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.Spinner;
import android.widget.ToggleButton;

public class MainActivity extends Activity {
    private ArrayAdapter<CharSequence> adapter;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        CheckBox checkBox = (CheckBox) findViewById(R.id.checkBox1);
        checkBox.setChecked(true);
        
        ToggleButton toggleButton = (ToggleButton) findViewById(R.id.toggleButton);
        toggleButton.setChecked(true);
        
        Spinner spinner = (Spinner) this.findViewById(R.id.planetsSpinner);
        CharSequence[] itemArray = getResources().getTextArray(
                R.array.planets_array);
        List<CharSequence> itemList = new ArrayList<CharSequence>(
                Arrays.asList(itemArray));
        
        adapter = new ArrayAdapter<CharSequence>(this,
                android.R.layout.simple_spinner_item, itemList);
        
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        
        spinner.setAdapter(adapter);
        
        findViewById(R.id.button1).setOnClickListener(
                new View.OnClickListener() {
                    
                    @Override
                    public void onClick(View arg0) {
                        EditText editTextName = (EditText) findViewById(R.id.EditTextName);
                        editTextName.setText("new Value");
                        
                        CheckBox checkBox = (CheckBox) findViewById(R.id.checkBox1);
                        checkBox.setChecked(false);
                        
                        RadioButton radioButton = (RadioButton) findViewById(R.id.radioButton1);
                        radioButton.setChecked(true);
                        
                        ToggleButton toggleButton = (ToggleButton) findViewById(R.id.toggleButton);
                        toggleButton.setChecked(false);
                        
                        adapter.add("another Item");
                        
                        adapter.notifyDataSetChanged();
                        
                    }
                });
        
    }
    
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
    
}

After this step you can run to test app before write unit test.

Step 4. Create a unit test

Create test folder in root project path.
Create package com.example.a3 in test folder.
Create MainActivityTest class in this package. 
package com.example.a3;

import java.util.ArrayList;

import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;

import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.Spinner;
import android.widget.ToggleButton;

import com.xtremelabs.robolectric.RobolectricTestRunner;

@RunWith(RobolectricTestRunner.class)
public class MainActivityTest {
    private MainActivity mainActivity;
    private Button button1;
    private EditText editTextName;
    private EditText editTextEmail;
    private CheckBox checkBox;
    private RadioButton radioButton;
    private ToggleButton toggleButton;
    private Spinner spinner;
    
    @Before
    public void setup() {
        mainActivity = new MainActivity();
        mainActivity.onCreate(null);
        
        button1 = (Button) mainActivity.findViewById(R.id.button1);
        editTextName = (EditText) mainActivity.findViewById(R.id.EditTextName);
        editTextEmail = (EditText) mainActivity
                .findViewById(R.id.EditTextEmail);
        checkBox = (CheckBox) mainActivity.findViewById(R.id.checkBox1);
        radioButton = (RadioButton) mainActivity
                .findViewById(R.id.radioButton1);
        toggleButton = (ToggleButton) mainActivity
                .findViewById(R.id.toggleButton);
        spinner = (Spinner) mainActivity.findViewById(R.id.planetsSpinner);
    }
    
    @Test
    public void shouldHaveValidPropertiesForFormElements() {
        
        Assert.assertEquals(button1.getText().toString(), "Submit");
        Assert.assertEquals(button1.getHint().toString(), "Touch for submit");
        
        Assert.assertEquals(editTextName.getText().toString(), "");
        Assert.assertEquals(editTextName.getHint().toString(), "Full Name");
        
        Assert.assertEquals(editTextEmail.getText().toString(), "");
        Assert.assertEquals(editTextEmail.getHint().toString(),
                "example@email.com");
        
        Assert.assertEquals(checkBox.isChecked(), true);
        Assert.assertEquals(checkBox.getText().toString(), "CheckBox");
        
        Assert.assertEquals(radioButton.isChecked(), false);
        Assert.assertEquals(radioButton.getText().toString(), "RadioButton");
        
        Assert.assertEquals(toggleButton.isChecked(), true);
        
        Assert.assertEquals(spinner.getAdapter().getCount(), 8);
        
    }
    
    @Test
    public void pressingTheButtonShouldChangeValueOfSomeElements()
            throws Exception {
        checkBox.callOnClick();
        button1.performClick();
        
        Assert.assertEquals(editTextName.getText().toString(), "new Value");
        Assert.assertEquals(checkBox.isChecked(), false);
        Assert.assertEquals(radioButton.isChecked(), true);
        Assert.assertEquals(toggleButton.isChecked(), false);
        Assert.assertEquals(spinner.getAdapter().getCount(), 9);
    }
    
}

Step 5. Configuration and run 

 - Configurate build path
   - Right click a3 project
   - Select "Refesh"
   - Right click a3
   - Select "Build Path" => "Configure Build Path..."
   - Add JUnit library on library tab
   - Add robolectric-X.X.X-jar-with-dependencies.jar (remember! - using dependencies for this tutor)
   - Add android.jar from <your android install directory>/platforms/android-17/android.jar
   - Add maps.jar from <your android install directory>/add-ons/addon_google_apis_google_inc_17/libs/maps.jar
 - Configurate and run test unit
   - Go to "Run" => "Run Configuration"  
   - Double click "JUnit" (not "Android JUnit Test")
   - Name: a3-test
   - Select the "Run all tests in the selected project, package or source folder:" radio button
   - Click the "Search" button
   - Select "a3"
   - TestRunner: JUnit 4
   - Click on the link "Multiple launchers available Select one…" at the bottom of the dialog
   - Check the “Use configuration specific settings” box
   - Select "Eclipse JUnit Launcher"
   - Click "OK"
   - Click "Run"
